Specification of Letters Patent.

Patented Aug. 199, 19113.

Application. filed (Ectober 10, 191.2. Serial No. 724,9?2.

T 0 all whom t may concern:

Be it known that l, )VAI/ran E. Huarternnn, a citizen of the UnitedStates, residing wat Cincinnati, in the county of Hamilton and State ofOhio, have invented certain new and useful Improvements inHydrocarbon-Burners; and I do hereby declare the Jfollowing to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertaius to make and use thesame.

This invention relates to improvements in hydrocarbon burners andparticularly to such as are adapted for use with oil stoves,- the objectof my present invention being to so construct the device as to keep theinner wick tube cool and reduce to a minimum thel undesirable effect ofsudden drafts of air, upon the flame on the wick.

)Vith this and other objects in View, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims. l

ln the accompanying drawings, Figure 1 is-a sectional. View of thedevice with the parts in their normal operative positions.

to cooperate with. suitable raising and lowering means. T he outer wicktube is provided at its upper end with an outwardly project ingdepressed flange or seat 7, and theinner wick tube is provided at itsupper end with an inwardly7 projecting flange 8, from the inner edge of.which7 a ring 9 projects upwardly. From the upper edge of said ring, ,anannular fiange or seat 10 projects inwardly and may be provided at itsinner edge with a depending rib 11.

The combustion. chamber member 2 compriseswconcentric foraminated shells12f-13 spaced from each other to form a combustion chamber 14 betweenthem, whichis in line with the wick. The shells are inclosed by a casing15 which is spaced from the outer shell 13 and is open at its upper end,the lower end of said .casing being provided with an inwardly projectingperforated Harige 16. The shells 12-13 and casing 15 are securedtogether by means of crossrods 17. i

4The lower end of the shell 13is seated (when the parts are in theirnormal working positions) upon the outer depressed flange or seat 7 atthe upper end of the wick tube 3. The inner foraminated shell 12 isprovided :1t-.its upper end with a perforated cap 18 and at its lowerend (which termi-. nates a short distance above the horizontal plane ofthe lower end of the shell 13) is provided with a perforated cap 19which rests (near its peripheral portion) upon the seat 10 at the upperend of the inner wick tube 4. Thus it will be seen that the foraminatedshells of the combustion chamber member are supported respectively, uponthe seats 7 and 10 of the wick tubemember, with the combustion chamberle immediately over and in direct alinement with the wick, and that theweight of the parts will in' sure the firm seating of said foraminatedshells.

The lower cap 19 is construct-ed with an annular series of radial lugsor fingers 20 and the lower end of the shell 12 is notched toaccommodate said lugs or fingers,--the4 lugs 21 formed by thus notchingthe lower end ot the shell being bent under the edge of the cap 19 andserving to retain the latter in place. The lugs or lingers 20 enter thecombustion chamber 14 and project a sufficient distance across the lowerportion of the same to be in line with the wick and constitute limitingmeans for the latter. From this construction, it will be observed thatthe wick limiting lugs or fingers are made integral with the lower capof the inner shelll 12 and that said lugs or fingers are thereforevertically movable with the combustion chamber member away from andtoward the wick, but that when the burner is in operation, saidlimiting. devices may be in more or less proximity to the wick(according to 4the adjustment of the latter) without detracting .fromthe eii'iciency of the flame on the wick.

A tube 22 is secured at its upper end to the lower cap 19 and,projecting downwardly through the opening formed by the rality of holes22a, and below said holes, a diaphragm 22b is fixed wit-hin said tube.With such construction, drafts of air directly through the tube will beprevented by the diaphragm 22h, the air entering the lower end of the`wick tube member being compelled -to pass upwardly through the spacebetween tho inner wick tube 4t 'and the tube 22 and plose' to said innerwick tube; through the holes 22a1and then upwardly through theperforated cap 19 into the inner ,shell of the combustion chambermember. With such construction, the inner wick tube will be kept cooland undesirable effects upon the flame by sudden draftslof air will bereduced to a minimum, the passage ofA air through the burner beingretarded and kept practically uniform. p

The tube 22 constitutes a guide for the vertical movements of thecombustion cham- `ber member, when the latter is raised or lowered bymeans of devices such as will now be described.

A ring 23 is located within the'cylindrical space formed by the innerwick tube and is provided with .arms 24 rigidly secured in any suitablemanner to the interior ofthe indiagonal edge, a horizontal seat 28 isformed and at one end of the lattei', a lug 29 projects upwardly so asto form a stop shoulder 30. At the side of `each arm 25 opposite thediagonal or inclined edge thereof, a horizontal slot 3l is formed,-thelower wall `of the horizontal slot in one arm `forming, in elliect, acontinuation of the inclined oi.' diagonal edge of the adjacent arm butat an angle to said edge.

When the combustion chamber member is in its normal operative position,the inwardl projecting pins 26 of the guide tube 22 wil be disposed inthe horizontal elon l gated slots 3l of the arms 24 and said combustionchamber member will be locked in its lower operative position. l/Vhen itis desired to raise the combustion chamber member above the wick tubemember, the operator will turn said combustion chamber meinber in onedirection so as to cause the pins 26 to ride on the inclined edges 27 ofthe arms 25. When the pins 26 shall have reached the upper ends of saidinclined edges, a fur ther turning movement or' the guide tube willcause said pins'to become disposed upon 'chamber member will besutlicien't to cause said pins to ride down the inclined edges and enterthe elongated slots bl, thus causing the coinbustion chamber member tobeco-ine disposed in operative position on the wick tube member and tobe locked in such position.

lVhile I have shown and described the manner of supporting thecombustion chamv bei' member on the wick tube member, and also wicklimiting means, l do not herein claim these features speciically,-thesame constituting the subject matter of my co'- operating applicationSerial No. 724,971.

Having fully described my invention what I claim as new and desire t0secure by Letters Patent, is:

l. In a hydrocarbony burner, the combination with a wick-tube member,and a combustion chamber memberhaving a perfol rated bottom cap, of atube secured to said bottom 'ap and movable in and guided by said wicktube member, said tube having holes below its upper end, and a diaphragmwithin said tube below the plane of said holes, the wall of saidl tubebelow the plane of said. diaphragm being in'iperforate.

2. In a hydrocarbon burner, thel combination with a wick tube member,and a. coinhustion chamber member provided with a perforated bottom cap,of a tube open at both ends and provided with holes near its upper end,said tube secured to said bottom cap and entering and guided by the wicktube i'neinber, a. diaphragm within said tube below the plane of saidholes, and raisingv and lowering devices secured within the wick tubemember, said raising and lower-l ing devices entering said tube andcoperating therewith to raise or lower the combustion chamber memberwhen the latter is turned.

[n testimony whereof, l have signed this specification in the presenceoftwo subscribing witnesses.
